Several celebrities and activists took to social media this weekend to denounce Trump's unconstitutional and discriminatory Muslim ban.

Over the weekend, demonstrators took to airports across the country to protest Trump’s executive order to ban refugees and international travelers from several predominantly Muslim countries—specifically Iran, Iraq, Sudan, Syria, Libya, Yemen and Somalia—from entering the United States. Several travelers arriving from these countries were barred passage and detained in airports for hours, while other green-card holders who had travelled outside of the United States were prohibited from boarding their return flights.
